The following keywords may be used with the Options qualifier:
o [No]All
Indicates whether or not all collectible statistics (all
statistics for all areas) are to be collected. The All option
indicates that all statistics information is to be collected;
the Noall keyword indicates that only the base statistics
information is to be collected. You must also specify the
Output qualifier. Note: Logical Area information is not
written to the binary output file.
o [No]Area
Indicates whether or not the by-area statistics information
is to be collected in addition to the base statistics
information. When you specify the Area or Noarea option, the
Base statistics are implicitly selected. You must also specify
the Output qualifier.
When the Area option is specified, statistics for all existing
storage areas are written to the binary output file; you
cannot selectively choose specific storage areas for which
statistic information is to be collected.
The size of the by-area statistics output largely depends on
the total number of storage areas in the database, including
reserved storage areas. If the database contains a large
number of storage areas, it may not be advisable to use the
Options=Area qualifier.
Before you replay a binary output file that contains by-
area statistics, specify the following command to format the
display correctly:
$ SET TERM/NOTAB
You can then replay the statistics as follows:
$ RMU/SHOW STATISTICS/INPUT=main.stats
o Base (default)
Indicates that only the base set of statistics is to be
collected; this is the default Options option. The base set of
statistics is identical to the one collected prior to Oracle
Rdb V6.1. You must also specify the Output qualifier. You
cannot specify Nobase.
o Compress
Compresses the statistics records written to the output
file specified by the Output qualifier. While replaying the
statistics, the RMU Show Statistics command determines if a
record was written using compression or not. If the record was
written using compression it is automatically decompressed.
If compression is used, the resultant binary file can be
read only by the RMU Show Statistics command. The format and
contents of a compressed file are not documented or accessible
to other applications.
o Confirm
Indicates that you wish to confirm before exiting from the
utility. You can also specify the Confirm option in the
configuration file using the CONFIRM_EXIT variable. A value
of TRUE indicates that you want to confirm before exiting the
utility and a value of FALSE (the default) indicates you do
not want to confirm before exiting the utility.
o Log_Stall_Alarm
If Log_Stall_Alarm is present when using the Stall_Log
qualifier to write stall messages to a log file and the
Alarm qualifier to set an alarm interval, only those stalls
exceeding the Alarm specified duration are written to the
stall log output file.
o Log_Stall_Lock
If you use the Stall_Log qualifier to write stall messages to
a log file, use the Nolog_Stall_Lock option to prevent lock
information from being written to the log file. If you use or
omit the Log_Stall_Lock option, lock information is written to
the log file.
o [No]Row_Cache
Indicates that all row cache related screens and features of
the RMU Show Statistics facility are to be displayed. NoRow_
Cache indicates that these features are disabled.
o Screen_Name
Allows you to identify a screen capture by screen name. If you
issue an RMU Show Statistics command with the Options=Screen_
Name qualifier, the screen capture is written to a file that
has the name of the screen with all spaces, brackets, and
slashes replaced by underscores. The file has an extension of
.SCR. For example, if you use the Option=Screen_Name qualifier
and select the Write option on the Screen Transaction
Duration (Read/Write), the screen is written to a file named
TRANSACTION_DURATION_READ_WRITE.SCR.
o Update
Allows you to update fields in the Database Dashboard. See
the Performance Monitor Help or the Oracle Rdb7 Guide to
Database Performance and Tuning for information about using
and updating the Database Dashboard. You must have both the
OpenVMS WORLD and BYPASS privileges to update fields in the
Database Dashboard.
o Verbose
Causes the stall message logging facility to report a stall
message at each interval, even if the stall message has been
previously reported.
NOTE
Use of the Options=Verbose qualifier can result in an
enormous stall messages log file. Ensure that adequate
disk space exists for the log file when you use this
qualifier.
You can enable or disable the stall messages logging Verbose
option at run time by using the Tools menu and pressing the
exclamation point (!) key.
You can also specify the Verbose option in the configuration
file by using the STALL_LOG_VERBOSE variable. Valid keywords
are ENABLED or DISABLED.
Lock information is displayed only once per stall, even in
verbose mode, to minimize the output file size.
